Share
1. Straining: One way is to use a fine mesh sieve or a dedicated tea strainer. Pour the brewed tea through this sieve to catch the leaves, keeping the liquid tea leaf-free.
2. Tea Infusers or Filter Bags: These tools are quite handy. When brewing, place the tea leaves in an infuser or filter bag. After steeping, simply remove the infuser or bag to enjoy leaf-free tea.
3. Decanting: Carefully pouring brewed tea allows the leaves to settle at the container’s bottom. By pouring slowly, you can avoid transferring the leaves into your cup.
4. Centrifugation (Industrial): In larger-scale settings, centrifugation involves spinning the brewed tea to separate the leaves using machinery.
5. Cold Brew Method: Steeping tea leaves in cold water causes them to settle naturally. After steeping, pour the tea, leaving the leaves behind.
Each method caters to different preferences and equipment availability. Whether using a strainer, infuser, decanting, or specialized machinery, one can savor tea without the hassle of leaves based on their chosen technique.
